Insider Look - 450 HP, 6.2L Gen V LT1
At first glance, the overall LT1 doesns't look much different from a typical LS3. But this cool, see-through view reveals how GM engineers cleverly integrated the solenoids and injectors into the area underneath the intake manifold. The engine is all aluminum, of course, integrating the latest in gasoline-engine technology with a two-valve, pushrod configuration. The direct-injection system increases the fuel pressure to 2,175 psi at the injectors.

Wonder when we can get crate engines?

ad a dry sump and off to the track

Add a standalone to the dry sump. The direct injection is nice, but not sure any of this is worth it/makes sense for a typical track car, given what is already available.
Will be interesting to see if you can get those heads on an LS3 and run the DI system with an existing PCM.

PCM issues, crap forgot about that.

Will be interested to see if this new engine will handle Hoosier R's on VIR and blow up after 20-30 HPDE events. Would make a super crate motor if it has LS6 reliability.

AU N EGL

that is what I was thinking too.

Should be an awesome engine. Can't see trying to adapt the factory DI to a GEN 4 you need block provisions and a camshaft to drive the DI pump. Coated bearings, piston squirters and its supposed to have forged rods instead of powdered metal should really help reliability

I'm interested in how well the oiling system works under g-loading. This is where the LS2,3,7 seems to lack. Also, need quality valvetrain components throughout. Some of the LS7 seem to have excessive valvetrain wear even on the street w/low miles.

I am not sure why the LS7s are having valve guide issues as their rocker geometry is pretty good, other than for a donkey dong cam.
I would assume the LT1 mirrors the LS3 - add in the cost of dry sump, lifters and real roller rockers if you want to rock and roll.
